目的 了解空军机务人员营养体质状况,有针对性地加强卫生保健工作。方法 对256名机务人员做膳食调查、营养状况体格检查和生化检查。结果 热能摄入量14 973.49 kJ/d,略低于规定标准(15 297.33 kJ/d);三大营养素热比分配合理;其他营养素的摄入量大部分能满足体内需要,但硫胺素、核黄素和钙摄入量不足,4 h饱和尿试验发现硫胺素、核黄素和抗坏血酸排出量偏低者分别占受检人员的79.6％、88.7％和15.1％;血红蛋白、血磷、血铁均正常;血清前白蛋白检查56人中14人低于国内报道的正常值低限;血钙检查56人,55人低于正常;体检发现瘦弱型体质者占受检人数的17.88％。结论 与1988年相比,1996年机务人员膳食营养状况和体质有所改善,但硫胺素、核黄素及钙营养不足与缺乏仍然突出。
Objective To understand the nutritional status of Air Force crew members and to strengthen health care in a targeted manner. Methods 256 crew members were investigated for their diet, physical status and biochemical tests. Results The energy intake was 14 973.49 kJ / d, which was slightly lower than the standard (15 297.33 kJ / d). The distribution of the three nutrients was reasonable. Most of the other nutrients could meet the needs of the in vivo. However, Riboflavin and calcium intake was insufficient, 4h saturated urine test found that thiamine, riboflavin and ascorbic acid emissions accounted for 79.6%, 88.7% and 15.1%, respectively; the hemoglobin, phosphorus, blood iron were normal ; Pre-serum albumin examination in 56 of 14 people lower than the national report of the lower limit of normal; 56 serum calcium, 55 were lower than normal; physical examination found that the number of thin-type constitution accounted for 17.88% of the number of subjects. CONCLUSIONS Compared with 1988, the dietary nutrition status and physique of crew members improved in 1996, but the lack and deficiency of thiamine, riboflavin and calcium nutrition are still outstanding.
